“…In general, the main type of microplastics in the three samples was PP, accounting for more than one third, followed by PA6 (about 28%), PET (25%), and PVC (12.5%), that is, PP > PA6 > PET > PVC. Therefore, PP is the main microplastic in the soil of this area, which is consistent with the observation by Liu Mengting et al, that most of the microplastics in the suburbs of Shanghai are PP (50.51%) . The prevalence of PP in farmlands has a certain relationship with its source.…”

Microplastics pollution is becoming one of the most serious threats to the surface ecosystem of the earth; it is widespread in oceans, rivers, sediments, soils, and organisms. It is a growing concern as an environmental pollutant, which currently has no clear detection standard. Detection methods still need to be constantly supplemented and improved. This study explored a novel method called time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) in this field. Four types of microplastics in farmland soils, namely, polypropylene, polyvinyl chloride, polyethylene terephthalate, and polyamide 6, were successfully identified in terms of particle size and abundance by combining the high molecular specificity with ion imaging capability of ToF‐SIMS. The procedure based on ToF‐SIMS analysis also provides a methodological reference and basic data for the investigation and research of microplastics in soil, coastal beaches, and sediment.

“…One essential component of terrestrial ecosystems is soil, and they experience strong pollution pressure. Microplastic contamination of soils is being increasingly documented, with potential consequences for soil biodiversity and function [49,99,108,145,197,198]. However, the ecological impacts of microplastics in soils have been well reviewed [25,203].…”

Microplastic–toxic chemical interaction: a review study on quantified levels, mechanism and implication

et al. 2019

Current problem facing researchers globally is microplastics as well as toxic chemical pollution of the ecosystem. Microplastics carry toxic chemicals in the ecosystem serving as a vector for transport. In this study, a review of the literature has been conducted with the following objectives: (1) to summarize the concentrations of toxic chemicals such heavy metals and hydrophobic organic contaminants sorped on microplastics; (2) to evaluate their spatial distribution regarding adsorbed contaminant; (3) to discuss plausible mechanism by which microplastics adsorp or desorp toxic chemicals in the environment; (4) to discuss implications of their occurrence in air, water and soil media; and (5) to discuss the impact of ingested microplastics to human health. Microplastics are ubiquitous environmental contaminant. Concentrations of sorped toxic chemical varied by location which represents a local problem; industrialized areas (especially areas experiencing crude oil-related activities or have history of crude oil pollution) have higher concentrations than less industrialized areas. Ingestion of microplastics has been demonstrated in a range of marine and soil organisms as well as edible plants, thus possibly contaminating the base of the food web. Potential health effect to human is by particle localization, chemical toxicity and microbial toxins. We conclude by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.

“…MPs are considered an emerging pollutant 3 because they have strong abilities to become enriched in heavy metals 4,5 and persistent organic pollutants (POPs) 6,7 and can affect the growth of organisms 8 . Since 2013, extensive data have been accumulated on the spatial distribution of MPs in coastal areas 9,10 , oceans 11,12 , rivers 13,14 , lakes 15,16 , sediments 17,18 and soil 19,20 . MPs have been found in remote areas 21,22 , which confirmed that MPs could be transported over long distances via the atmosphere 21 and ocean currents 12,15 , which makes MPs an extensive global pollutant.…”

Anthropocene 8,27,33,35 , but there is still lack of sufficient studies about (micro)plastics abundance and characteristics versus time. We selected the second-largest urban lake in China, Donghu Lake, as the study area and collected a sediment column. The MPs with a detection limit of 100 μm versus time were studied by the 210 Pb chronological data, Raman Spectrometer identification and scanning electron microscope. The changes in MPs abundance, length, colour, polymer type, and surface features over time were studied, and the possibility of using MPs as an indicator of the Anthropocene was discussed.
